Designed for Science On a Sphere, this video explains the ozone hole over Antarctica - the annual thinning of stratospheric ozone caused by manufactured chemicals. 25 years after the Montreal Protocol limited the use of ozone depleting chemicals,... (View More) scientists are starting to see signs of recovery. ClimateBits videos are designed for Science On a Sphere (SOS) and also available on YouTube. Links are provided to more information for this topic from the main ClimateBits website (see related & supplemental resources). (View Less)
This video explains the stratospheric ozone layer. Protecting life on Earth, ozone in the stratosphere is important because it absorbs most harmful UV radiation from the sun. The visualization shows how the thickness of the ozone layer varies with... (View More) air flow aloft and seasons and where biggest changes occur. ClimateBits videos are designed for Science On a Sphere (SOS) and also available on YouTube.

Emphasizing the synergies between science and engineering, these video clips highlight the research of professional ocean scientists and engineers in various disciplines. The clips are accompanied by additional relevant content including images,... (View More) data visualizations, graphs, animations, and other information. Content has been organized into more than a dozen thematic areas such as Solving Old Problems with New Technology and Small Scale Observations and Large Scale Ideas. All content has been aligned with science and engineering practices from the Next Generation Science Standards, including "asking questions and solving problems" and "planning and carrying out investigations," providing applicable resources for teachers who want to provide role models of effective practice for their students.

This ChemMatters article provides a history of the study of ozone, a description of an experimental simulation called "The World Avoided," a brief introduction to the chemistry of ozone, an explanation of how ozone is measured, and the difference... (View More) between "good" ozone in the stratosphere vs "bad" ozone in the troposhere. ChemMatters is an educational magazine published by the American Chemical Society. (View Less)
This ChemMatters article provides a brief background on smog, then examines the causes of it, efforts to reduce it, and methods used to measure it. ChemMatters is an educational magazine for high school students.
This problem-based learning module places learners in the role of researchers analyzing carbon monoxide's environmental impact. Both vehicle emissions and biomass burning are cited as events producing carbon monoxide that impact the environment.... (View More) Instructions for accessing NASA data from four different sources are provided along with suggested resources and investigations for classroom use. This module was developed to be used in the Earth System Science Education Alliance (ESSEA) courses for middle and high school teachers and is also available to teachers to adapt for general classroom use.

In this activity, users examine satellite images from NASA's Total Ozone Mapping Spectrometer (TOMS) that show how much ozone is in the atmosphere over the Southern Hemisphere. They interpret the images to identify ozone thinning that develops over... (View More) this region each summer, and compare its size from year to year. Using freely-available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements into a spreadsheet program and create a graph to document changes in the size of the ozone hole. This chapter is part of the Earth Exploration Toolbook, which provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page. (View Less)
In this problem-based learning activity, learners investigate impact of sulfur dioxide on the environment. Sulfur dioxide comes from both human activities and natural sources. Burning coal and other fossil fuels is the largest source of sulfur... (View More) dioxide from human activities. Students have a choice of analyzing the impact of volcanoes’ emissions of sulfur dioxide on the environment; they can also investigate the idea of injecting sulfates into the atmosphere to counteract global warming. Instructions to access NASA data are provided along with additional resources and activities. This module was developed to be used in the Earth System Science Education Alliance (ESSEA) courses for middle and high school teachers and is also available to teachers to adapt for general classroom use.
